ncase [ɪn'keɪs] — enforce a case style

Why?

So that I could

% for f in *.pdf; do
	mv "$f" $(ncase -s `basename "$f" .pdf`).pdf
done

Binary

Install

% cargo install ncase

Usage

Enforce the chosen case style on a string and write it to the standard output.

% ncase --pascal this is a test string
ThisIsATestString

% ncase --lower ThisIsATestString
this is a test string

By default, enforces the random case.

% ncase this is a test string
ThiS IS A tesT stRINg

Library

Install

Add the dependency to your Cargo.toml.

[dependencies]
ncase = "0.1"

Or from the command line.

% cargo add ncase@0.1

Usage

Use the functions for one-off case conversions.

assert_eq!(ncase::camel("camel case"), "camelCase");
assert_eq!(ncase::snake("snake case"), "snake_case");

Use Words if you need to convert one string into many case styles.

use ncase::Words;

let s = "Lorem ipsum dolor sit amet";
let w = Words::from(s);

assert_eq!(w.kebab(), "lorem-ipsum-dolor-sit-amet");
assert_eq!(w.title(), "Lorem Ipsum Dolor Sit Amet");

Or if you want to use the separator regex.

use ncase::Words;
use regex::Regex;

let s = "Lorem, ipsum (dolor _sit)_ amet";
let sep = Regex::new(r"[\pP\s]+").unwrap();
let w = Words::with_separator(s, &sep);

assert_eq!(w.lower(), "lorem ipsum dolor sit amet");
assert_eq!(w.upper(), "LOREM IPSUM DOLOR SIT AMET");
